**Very well done Oskar!**

BUT WHERE ARE YOUR INSTRUCTIONS?

_Question_:
```rs
//Why am i actually doing a hashtable ???
//Im just saving to the file and closing the program?
//What point does the hashtable have??
//I started doing a loop cause then it would actually serve some purpose, but i guess if you can have a program with the hashtable in the background running then it would be fine??
//But i removed loop :(
//But is quite easy to implement again, since i saved the code
```

The issue discusses a Rust dummy DBMS assignment using files and a hash table, but names no documentation file, test, or entry point. First identify where this project's assignment instructions live and determine what explanation is missing; done should mean the purpose of the hash table and the assignment requirements are documented clearly.
